Applicationset and Application belong to the same namespace

[Hargeek]

I expect the application generated by applicationSet to use the same name, which requires it to be generated under a different namespace. Explain also has the namespace field

kubectl explain applicationset.spec.template.metadata.namespace
KIND:     ApplicationSet
VERSION:  argoproj.io/v1alpha1

FIELD:    namespace <string>

DESCRIPTION:
<empty>

In fact, it can only be generated to the same namespace as applicationSet
An error is as follows

time="2022-06-08T08:32:46Z" level=error msg="validation error found during application validation: ApplicationSet helloworld contains applications with duplicate name: helloworld"
time="2022-06-08T08:32:46Z" level=error msg="validation error found during application validation: ApplicationSet helloworld contains applications with duplicate name: helloworld"

Indeed, the examples in the reference documentation do not use namespace

Ran into this as well. It's surprising that the CRD does allow a namespace on the template but it doesn't appear to actually be used.
Sadly my golang isn't good enough to feel comfortable trying to fix this. Hopefully there's more interest out there to get this fixed.
